Wl.'l10h the following 1s a speciiication.

My inv ntion relates to billing mechanism for typewriting machines and more partieu larly mechanism for doing condensed invention is to provide simple an efiicient billing'mechanism operative to. aid in mechanically positioning the platen and with the aid of which condensed record and other billing work can be" readily done without l'r'XiIlg themind of the operator with mental calculations or therecollection of given indioes' or numerals and without taxing the eyes'and mind of the operator in observing when parts are in certain positions each other. Another object of my invention is to provide sim lo and efficient mechanism in the nature 0 an attachment which can be readily applied to existing forms of typewriting,

machines without changing the structural 1 features of said machines.

' Astill further object of my invention is to provide billing mechanism for condensed record and other billing work in which the use of index numerals or indices may-gbe entirely dispensed with.

- To the above and hereinafter appear, my invention consists in the features of construction, arrangements of arts and combinations of devices to be hereinafter described and particularly-pointed out in the appended claims.

I have shown my invention applied to a No. 6 Remington typewriting machine to which machine my attachment maybe readily connected without materially changing the structural features of said machine; but it should be understood that the attachment may be ap lied to various styles of typewriting mac ines.'

Thetop matica'lly il-ustrated at 1, su ward'l'y projecting lugs or stam which a traverse rod 3 is mounted. A carriage truck 4 carries 'rollersj5 which cooper ate with the traverse rodBfand the truck supports the usual pa er table 6. Links 7 pivotally connect a p aten frame 8 to the truck 4 and the .forwardside of the platen frame carries a roller 9 which cooperates ports upards 2 on with the usual shift rail 10, the latter supporting the forward side of the platen frame. A platen 11 is mounted to rotate in the platen frame and a line spacing wheel 12 is connected to tli'e rightand end of the platen. A detent roller 13 is carried by the usual spring 14 v by a screw 14: the roller bearing a ainst the H teeth of the line spacing wheel. A ine space ing pawl 15 is pivoted at 16 to an actuating to a .downwardly anr forwardly extending bracket arm 19 on the platen frame. The lower arm ms! pawl may be actuated. A spring 21 ccsecured to the platen frame 20 of the lever V 17 serves as "a handle by which the line spacas to bring any one of the contact faces 23- i into the path of the tail 22of the line spacing platen which is connected therewith.

pawl, and thus determine the extent of line spacing movement which may be transmitted to the line spacing wheel and the A platen shaft 28 is received. in the hearing at 'struction being sue the right-hand end of the platen frame and extends therethrough, and a finger wheel 29 -is connected to said shaft by a screw 30. A platen head 81 at the left-hand end of the platen is of essentially the usual construction and'is secured by wood screws '32 to the wooden core 38 of the platen. The platen head has an outwardly extending huh or boss 34, said boss being slightly shorter than that usually provided (Fig. 2). A'central opening extends through the platen head and boss and through said opening passes the platen shaft 28, said shaft being secured to the platen head by a screw 35 which is received in a threaded opening in the boss 34 and bears at its inner end against the shaft 28. A disk 36 is provided with a cylindrical hub 37 which extends from the outer face of {she platen head 31 to the inner face of the sit 8 (Fig. 2); This hub is mounted in art on the boss 34 of the laten head 3]., t 1e conh as to afford a turning movement of the platen independently of the hub and the disk carried thereby. An

opening 38 is formed in the hub 37 th access to the screw 35 which connects the platen head 31 to the shaft 28. A threaded opening is provided in the hub 37, on the outer side of the disk, to receive a screw 39, the inner end of said screw bearing against a sleeve 40 which extends through and turns freely in a bearing opening in the platen frame. The platen shaft 28 extends through said sleeve and. projects'beyond the outer end thereof. 1

The disk 86 provided with a circular series of locking openings 41 (Figs. 1 and 2) which extend transverselytherethrough and are )refcrably equal in number to the teeth of the line spacing wheel and correspond-in spacing to said teeth thus, if the line spacing wheel be provided withthirty-tl1ree teeth the disk 36 will have thirty-three openings 41 circularly arranged and the spacing between which corresponds to the s acin'g between the teeth of the ratchet wieel.

land side or end bar of the platen frame On each side of the disk 36 is mounted a stop member;

races such as that shown in detail in Fig. 4. Said stop member comprises a ring-like body portion 42 which surrounds the hub 37 at one side of the disk, the'opening in the ring-like member- 42 having substantially the same diameter as the hub. The inner edge of the opening in the ring may be beveled or rounde as indicated at 43 for purposes whichwill hereinafter appear. A stem-like portion or shank 44 projects from the ring 42 and carries a stop 45 at its outer end, said step preferably projecting laterally over the periphery of the disk, as shown in Fig.2. The stop on the member at the inner side of the disk is numbered 45 while the stop on the member at the outer side of the disk is nu1nbered'45.

A laterally projecting in 46 is carried by the arm 44 and is adapted to be seated in any of the openings 41 in the disk 36.

A coiled expansion spring 47 surrounds the hub 37 and bears at one end against the platen head and at its opposite end against the ring 42 of the inner stop member so as to force the stop member outwardly towards the disk and maintain it locked in place with the pin 46 seated in one of the engaging openings in'the disk. A second coiled spring 48 surrounds the outer portion ofthehub 37 and bears at one end against the ring-like portion of the outer stop member and at its other end against a washer 49 which. surrounds the hub and bears against theinner face of the left-hand end bar of the platen frame. This spring tends to force its associated stop member inwardly towards the disk and to maintain the locking pin 46 seat ed in one of the engaging openings 41.

In order to effect an adjustment of either of the stop members on the disk it is merely necessary to press against the stop portions 45 or 45 in a direction opposite to that in which pressure is ap )lied by the associated spring. The beveled or rounded edges '13 ofthe ring portion will afford a slight swinging movement of the stop member a ainst the tension of its associated spring, sufiicient to enablethe pin 46 to be disengaged from the opening 41 in which it isseated. stop member may then be turned around the hub and the pin 46 may be engaged in another opening 41 to secure the stop mem- The her in its newly adjusted position. By

mounting the stops 45 and 45" (together) with their carrying portions on opposite sides of the disk 36 either of thestops maybe adjusted on the disk relatively to the other without interference from the. other stop or themember which carries it.

The sleeve 40 which, as hereinbefbre explained,'is receivedin a bearing opening in the platen frame and supports the platen shaft at the, lefthand end thereof is rigidly connected. by the set screw 39 to the disk and the stops carried thereby. The outerv free end of this sleeve has a clutch member 50 3. I locking iece59 ivotedthereto at 60 and ger piece 61 by which it 'securedthereto, said clutch member being clearly gshown in Figs. 2, 5 and 6.- fTh Q clutchfniernber may be inthe'nature of ne,

ection of atjt'wopart finger? wheel, said sec-l .tion 50. hav1ng a'central opening or de' res .v

"sion 51: therein." The side walls 52 ,'o the opening arejin'clined and constitute an engaging or clutchface which co6perates with ted to re-' ceivea slight movement longitu inal of the i provide with a which has a threaded stem 56 'a f said' stem cofiperating with a tapped opening in the end of the platen shaft 28. A laterally pro'ecting spline 57 extends from the stud 55' platen on a' cylindrical beazing l stud '55 an is rece1ved in a groove in the finger wheel 54. Thespline 57 may be driven into a longitudinally,extending groove in the stud alt ough .the finger wheel-iscapable of a slight independent movement lfiigitudinal of the platen.

r The outerend of the bearing stud 55 is bifurcated at 58 for ,the reception of acam or may be mani ulated. A'recess'or opening 62 is provide in the finger wheel for the reception of an expansion spring 64 whichsurrounds the platen shaft and bears at one end .7 aga nst the'outer end of the sleeve and at itsother end a ainst the bottom wall of the openin 62. he ressure .of this spring is exerte to force t e-two clutch members apart, as shown in ,Figs. 2 and 5, when the cam or lockingpiece 59 is moved to the position shown in said figures' When, however,

the cam piece is moved to the position'shown in Fig. 6 the cam edge 65, durln such move- I mentfwill cooperate with an e ge 66 of the finger wheel are all locked to rotate together} other end of the platen, may be cmployedtobearing opening in the finger wheel 54 .to force saldfinger wheel. to the right so that the two members 50 and 54 of the clutch will be brought into ri id clamping engagement as shown in Fig; 6. ith the parts disposed as shown'fin said figure, the platen, the disk 36, the steps 45 and 45. and the two part When, however, the cam device 59 is moved to the position shown in Figs. 2 and 4 the finger wheel 54 will be moved outwardly to release the clutch members, thus effecting a disconnection between the platen and the rotary stops-45 and 45. At this time the finger wheel 54, or the finger wheel 29 at the turn the platen indr-spendently of the rotary stops 45'aud 45 and the disk which carries them.

55 and held therein by a drive fit. The con' struction is such'that the platen shaft and fin er wheel are caused to rotalxe together stop 67 which is in the nature of a "bracket arm may be'secured in place on the platen frame by any suitable means such as V the screws 68 and 69. This stop is secured to the front bar of the platen frame near the lefthand end of the platen and projects rear- :wardly so that the free end thereof will pro-- 'ject into the path of the rotary stops 45 and 45 (Fi s. 1 and 3).

It W'll be understood that when the ca m piece '59 has been moved to the position illustrated in Fig. 6 to' effect a locking engagemerit .between the clutch members, thjj'e' rov engagement with the fixed stop 67 an further forward rotation of the platen cannot "take place until the clutch members ,are disengaged. In alike manner the platen is arrested during its rearward rotation when thestop 45 comes .in contact with ,the fixed stop 67, and further rearward or backward rotation cannot be effected without releasing the clutch members.

It will be seen that the movement of the finger Wheel 54 into and out of clutching engagement is a movement longitudinal Y of the platen and may beefiected while the platen isat rest and without disturbing-the rotary stops and r'nay be effected while either of the rotar steps is in contact with the fixed stop67.-" t will also be seen that the cam iece 59 not only constitutes means for efecting a clutching engagement between the clutch members but that it also constitutes locking means for maintaining the clutch members locked to ether and for maintaining the rotary stops loc ed to the platen, and that the clutching means enable the platen to be positively arrested by'the stop devices or to be freed from arrest by said stop devices at will.

In doing condensed record work, bill or invoice sheets of a given character are employed and a copy of the different items as 'they are typewritten on the various bills is 2 ployed. This may be accomplished as follows :The clutch members 50 and 54 being disengaged, the disk 36 may be turned by the section 50 of the two-part fingerwheel until the stop 45 is brought into engagement with the fixed stop 67, as shown in Fig. 1. A. bill or invoice sheet, a "condensed record sheet, and interposed carbon sheet, are then entered in the machine with the leading edges of said sheets together and the record. sheet next to the platen andwith the leading edges of the sheets at the points where the feed rollers a contact with the platen. The clutch members are then clam ed together and the platen is turned until the part of the bill or invoice where the first line of writing is to appear is brought to the printing line. This is determined in the first instance by'swinging the platen frame back and observing when the point or line in. question reaches the printing line. The forward feed movement of the platen just described is effective to carry the stop 45 away from the fixed stop 67 a distance corresponding to the extent of rotary movement that has been given to the platen in feeding the invoice, .carbon and record sheets forward. The part of the in.- voice sheet where the first line of writing is to appear having been brought to the printing line in the manner described, the stop 45 is now adjusted on the disk 86 to a position where it will contact with the under side of the fixed stop 67 and said stop 45 is then looked to the disk. It may be assumed, that the relative adjustment between the stops 45 and 45* corresponds to that shown in Fig. 1.

, The cam device 59 may then be moved to the position shown in Figs. 2 and 5 to release the clutch members and the operator may then roceed to write the hill or invoice and a caron copy of it will be produced on the condensed record sheet. During the forward rotation of the platen in writing the various items on thebillrsheet, the stop -15 will be maintained in contact with the stop 67 while the platen is traveling independently of said stops. This maintenance of the stop in contact with the stop 67 is effected by the frictional contact between the hub of the disk 36 and the boss 34 on the platen head 31. When the invoice sheet has been written the operator will effect a double line space movement of the platen in order to provide a double line space on the record sheet between the last line of the hill just reproduced on the record sheet and the first line of the nixt sues.

cceding hill to be reproduced on the record I I shoot through the interposed carbon sheet.

'rotary stops 45 and 45 to turn with the platen. Either of the linger wheels 54 or 2!) may then be employed to give a reverse or backward rotation to the platen until it'is prevented from further movement in this direction by the contact of the stop 45 with the fixed stop 67 as shown in Fig. 1. This reverse rotation of the platen through a predetermined distance,- controlled by the rotary stops in cooperation with the fixed stop 67 is su fiicient to bring the platen back where a new invoice sheet may be introduced outside of the invoice sheet last written, In introducing the second invoic'e sheet the lead ing edge thereof should be brou ht to the points of engagement between the feed rollers and the platen. The platen is then'turned' forwardly until the stop 45* reaches contact with the fixed sto may be the last invoice sheet introduce 67 when it will be 'arrested. The clutc 1 is then disen aged and written as before, the platen at'this time turnin independently of the sto Sif VThen the bill has been'completed a dbuble line space movement of the platen is again ef= footed and the clutch devices are again forced into clutching engagement and a reverse rotation of the platen is given until the sto e5 is again brought into contact with the ed stop 67, as shown in Fig. 1. A new or third invoice sheet may then be introduced as bee fore outside of the invoice sheet last written and the laten may be given a forward rotation unti the stop 45* contacts with the fixed stop 67 and arrests the further movement of the platen in that direction. The clutch is then released and the operator proceeds to write the third invoice; and the carbon copy thereof which is produced on the condensed record sheet has its first line situated two line space distances from the last written line of the next receding record on the condensed recor sheet. This operation may continue indefinitely after the stops. 45 and 4-5 have once been. adjusted in the manner described. say three, have beenintroduced into the machine and written, the first written'invoice sheet will, during the forward movement of the platen, be fed to a position where it will be fed out of the machine, or where it may be readily removed without disturbing the other sheets. When one record sheet has been filled it may be removed from the machine together with the carbon and such written invoice sheets as there may be in the inachine. The clutch members 'being engaged and the stop 45 being in engagement with the fixed stop 67, a new record sheet, a' carbon sheet and new invoice sheet may be introduced into the machine as before and the platen may be turnedforwardly until the stop 45 contacts with the fixed stop 67. The

clutch is then released and the operator then proceeds to write as before.

be given a lead over the other sheets suf-' After a number of invoice sheets,

Instead of introducing a record sheet, ca'rdescription that after the stops 45 an 45 have been adjusted relatively to each other in the manner described they are maintained in fixed relation'and' determine the extent of backward and forward rotation which may be given to the platenwhen the rotary stops are connected to turn withthe platen and that during the o eration pf the machine in writing the clutc 'is disconnected and the laten turns independently of the stops.

he only operation involved in determiningthe-extent of backward rotation sufiicient to I receive a new invoice or record sheet is to turn the platen backwardly until it is arrested by with the fixed stop after the c utch has been locked and the only 0 eration involved to 'determine the extent 0 forward rotation of the platen necessary to bring the first line of writing of! the last introduced bill to the printing point is to turn the platen forwardly until it is arrested from further movement by the stop comin into contact with the fixed stop 67. This orward and backward turning of the platen to predetermined extents, and until it is arrested by the cooperation of the stops, properly positions the sheets withlreference to each other and'relieves the mind of the operator from making any calculations orfrom observing any indices and greatly facilitates the speed and accuraoywith which the work'can be accomplished; the stops themselves inechanicall determining the extent of' rotation to :whic the platen may be moved in either direction. In Figs. 7, 8, 9 and 10 I have shown slightly modified forms of constructions embodying my invention! In the construction shown in the precedingfigures a clutching engagement between the parts50. and 54 is effected through frictional connection be tween said parts. In the construction shown in Figs. 7 and 8 I provide a clutch member which comes onds to the member 50 shown in the prece ing figures, except that a seriesof circularly arranged engaging teeth 70 is provided thereon for 006 eration with similarl arra ed teeth 71 on t e finger Wheel 54'.

herwise the parts may be constructed in essential] 'the same manner as that (previously described. It will be understoo ,thereforc, that the clutching engagement may be eflected between the parts either frictionally or'by positive means for connecting the rotary stops to the platen.-

'lifieithcr case, however, the. construction ords a rigid connection which revents a rotation of the lilaten when eit er'of the rotary stops ,is

the stop 45 comin into contact with the fixed stop on the platen frame. "In Figs. 9 and 10 I have shown a modified form of disk and rotary stops. In this construetion only one of the rotary stops is adiustable,

.' the ,stop 45* being formed integra with a disk 36. The peripheryoithe' disk in this case is provided with a series of squared teeth 72, with spaces 73 between them in which a locking flange 74.- of an adjustable stop member is adaptedto be seated. The number of the teeth 72, or of the space between them, corresponds substantially to the number of teeth of the line spacing looking flai e 74 in t 1e recess 7 3 in which it i is seated. he lockin flange projects beyond the periphery of the teeth 72, as shown in Fig. 10, and constitutes a stop 78 which 006 erates With a fixed stop 79 on the frame of t e machine. The operation of this construction is similar to that shown in the preceding figuresand further description thereof is deemed unnecessary.

It will be observed that it is unnecessary to make any essential changes in the construction of the typewriting machine in order to apply my invention thereto. The platen shaft 28 may be the ordinary platen shaft of the machine with a tapped opening in the end thereof for the rece tion of the threaded stem of the bearing stuc 55. However, if desired the so-called bearing stud 55 and the shaft 28 may be made in one piece. A slightly enlarged bearing opening ma be made in the left-hand end or side bar 0 the .platen frame to receive the sleeve 40 and the usual sleeve such as 34 on the platen head 31 may be out off for a portion of its length to pects of my invention'any suitable means may be employed for this purpose. However, I refer to provide some means such as those s own for effecting such'relative angular ad'ustment, so that the stops may be ad-' juste to different points that correspond to rought into cooperation the spacing between the teeth of the line spacing ratchet wheel, because each of the adjustable stops may then always be set at a point where it will arrest the platen, in its back or forth rotary movemcn t, in line space position or will arrest the platen at a point where the detent roller 13 is properly seated between two teeth of a line spacing wheel and not at a point where the detent roller bears on the crown of a tooth of said line spacing wheel. If the platen..wer e arrested in this last mentioned position a slight accidental displacement of the platen might be effected which would result in the improper positioning of the platen, and for this reason l prefer to employ some means such as thosedcscribed for effecting the positioning of the adjustable stop or stops at a point or points which will correspond to a line space position when the platen is arrested by the cooperation of the stops. Furthermore, the carrier 36 (or 36) need not necessarily be in the form of a disk, but may be of segmental or other form, since in condensed billing work it seldom, if ever, ccurs that an angular adjustment of one of the stops 45, or

78 throughout 360 is required.

From certain aspects of my invention the locking device 59 may be dispensed with. and.

the finger wheel 54 may be moved and held in the clutching engagement by hand. 1 prefer to employ a locking device such as 59 since it enables both hands of the operator to be employed at all times and the same amount of care need. not be exercised in rotating the platen back and forth as would be necessary if a locking device was not em ployed. When the locking device 59 is dispensed with it may also be found desirable to dispense with the spring 64 and depend on the hand of the operator to move the finger wheel longitudinally of the platen into and out of clutching engagement and to de pend upon the frictional engagement between the parts to maintain the finger wheel in either shifted position to which it is moved by hand.

While the devices of my invention are in-- tended primarily for condensed record work they may be employed for other purposes and for other forms of billing work. It is not deemed necessary to describe the methods of procedure under the various uses to which the invention may he put but it may be well to point out that it may be employed in facilitating the writing of bills or invoices or accurately filling in partly printed blanks, and that by its aid the work sheet may be accurately and mechanically positioned in the machine to receive the type impressions at the proper .point or points so that uniform, neat and properly positioned work on the various bill heads or other blanks may be done.

Various changes may be made without departing from my invention.
